GALF-WEANER.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed December 6,1906. Serial No. 346,602

To all whom it may concern:

Be it known that I, O'r'ro IIORTHRIDGE PETERSON, a citizen of the United States, residing at Minneapolis, county of Hennepin, State of Minnesota, have invented a certain new Improvement in Calf-Weaners, of which the following is a specification.

My invention relates to calf weaners of the class which are adapted to be held by the septum of the calfs nose or the dividing cartilage, and the object of my invention is to provide means whereby the device may be applied to or removed from the calfs nose instantly; and to make said device of as few parts and as strong as possible.

A further object of my invention is to provide a perfectly plain device without any spurs, prongs or anything to injure the calf, or the mother, when the calf attempts to nurse.

A still further object of the invention is to make the device in such light and smooth manner that it will not render the cartilage of the calf s nose sore, and further to provide means to prevent the device from swinging upward above a certain point, for reasons hereinafter described.

To this end the invention consists of constructions and combinations which are hereinafter described and more particularly set forth in the claims.

Referring to the accompanying drawings, Figure 1 is a perspective view showing the device attached to the animal. Fig. 2 shows the device detached, or opened, ready to be applied. Fig. 3 is a top elevation. Fig. 4 is a sectional view taken on the line B B of Fig. 6. Fig. 5 is a sectional view taken on line A A of Fig. 2. Fig. 6 is a side elevation of the device. Fig. 7 is an end elevation. Fig. 8 is a sectional view taken on line X X of Fig. 6. Fig. 9 is a sectional view taken on line Y Y of Fig. 6. Fig. 10 is a sectional view taken on line Z Z of Fig. 6. Figsjll and 12 are modifications.

The device is composed of two plates 1 and 1 of tin or other suitable material, which are made rigid by the ribs 2 forming therein. The plates 1 and 1 overlap and are pivotally secured to each other by a pin 3, and are recessed at 4 for the reception of the animals nose.

At the top of the device and rigidly secured to the plates 1 and 1 are fingers 5, extending partially across the recess 4 and adapted to engage the nostrils of the animal. The fingers 5 are provided with septum-em gaging balls 6 which are adapted to rotate on the fingers 5 so as to cause as little friction as possible on the cartilage of the animals nose.

The object of the pivoted connection between the plates 1 and 1 is to permit the nostril-engaging fingers 5 to be brought toward or away from each other when attaching or detaching the device. When the plates 1 and l have been brought together in a closed position they are automatically locked in place by a catch consisting of a raised inclined projection 7 formed in plate 1. The projection 7 is provided with a shoulder 7 that engages the plate 1 when the plates are in a closed position. The elasticity of the plates 1 and 1 is sufiicient to permit the plates to spring apart to let plate 1 pass over the projection 7 when said plates are turned on their pivot and fingers 5 are brought together. To open the device before attaching to the animals nose plate 1 is forced outward away from plate 1 thereby releasing the plate 1 from the shoulder 7 The plates may then be turned on their pivot thereby throwing fingers 5 apart as shown in Fig. 2 after which the device is placed in position over the mouth of the animal and the plates 1 and 1 are turned back on their pivot and the fingers 5 will enter the nostrils and engage opposite sides of the septum. The catch will then have sprung into place as shown in Fig. 4 and will securely lock the plates together in closed position as shown in Fig. 6.

The plates 1 and 1 are bent outward at the top leaving the recess 4 and forming a cup-shaped arch 8, which spans the said recess 4 when the edges abut in closed position, and is adapted to engage the animals nose and thereby limiting the upward movement of the device if same should be forced upward when the calf attempts to nurse.

In Fig. 11, I have shown plates 1 and 1 reinforced by means of frame 9 which is cut from heavy sheet metal and secured to said plates, in which case plates 1 and 1 are made of very light material in order to obtain lightness.

In Fig. 12, I have shown plates 1 and 1 pivoted near one end in order to get the outwardly curved portion 8 formed in one plate thus avoiding the abutting edges in said outwardly curved portion 8.

It will be observed that there are no sliding nostrilengaging tongues or fingers, nor detachable pins or screws about the device which have to be loosened, but instead, the plates 1 and 1 may be grasped and forced to turn on their pivot thereby disengaging the nostril-engaging fingers 5, which are stationary to the said plates, from the nose of the animal.

It should be understood that the device does not pre vent the calf from grazing inasmuch as when the animal lowers'its head the device swings outwardly and allows of free access to grass-or other vegetation and it drops back into position when the animals head is raised.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is:

1. In a device of tlre class described, the combination of plates 1 and 1, the pin 3 forming a pivot for the said plates, the fingers 5 rigidly secured to the plates 1 and 1; the inclined projection 7; and the shoulder 7; substantially as set forth.

2. In adevice of the class described, the combination of the plates 1 and l; the pin 3 forming a pivot for said plates; the ribs 2 and arch 8 formed integrally in the said plates; the fingers 5 rigidly secured to the said plates 1 and 1'; the inclined projection T; and the shoulder 7; substantially as set forth.

In testimony whereof I hereunto afiiix my signature in presence of tWo Witnesses.
